英语词汇eager beaver的起源、历史背景-英语词源词典

eager beaver. Referring, of course, to the industrious beaver, this near-rhyming expression is a Canadian Army one that isn’t recorded before 1940, although it obviously derives from such phrases as “as busy as a beaver,” which dates back to the early 18th century. Unlike the early expression, however, eager beaver is usually applied derisively to someone who is overly industri- ous, zealous, gung ho in his work, one who tries to impress his superiors by his diligence and becomes obnoxious to his asso- ciates as a result. See beaver.
